Product Description

ASTM 1/2" Stainless Steel coil tube, 316 Stainless Steel Coil, Stainless Steel Tubing Coils, Stainless Steel Coil Tubing, Coil Stainless Steel Tubing, 316l Stainless Steel Coil, 304l Stainless Steel Coil.

Stainless steel coiled tubing is a compact type of tubing used in many different industries including chemical, petrochemical and food production. It is made of high-quality stainless steel, which has excellent corrosion resistance, heat resistance and pressure resistance. The piping is designed as a coil, making it very flexible and easy to install in tight spaces. Additionally, its small diameter means it can be used in applications where large pipes are impractical.

Stainless steel coils are commonly used in heat exchangers to transfer heat from one fluid to another. It is also used in the production of high-performance vehicles, such as racing cars and aircraft, where strength and durability are critical. Overall, stainless steel coiled tubing is a versatile and reliable material that can be used in a variety of applications.

📈 Working Pressure Charts (PSI)

⚠️ Technical Guidelines & Pressure Factors

ASME Code Standard: The ASME code suggests a safety factor of four when determining working pressures.

Applicable Material Standards: T304/L, T316/L, & T317L A269 Tubing for temperatures between -20˚F and 100˚F.

Example Calculation: For a 1/4” OD x .035” Tube = 21,000 PSI rating. Actual Safe Working Pressure = 21,000 PSI ÷ 4 = 5,250 PSI.

Temperature Multipliers: For higher temperatures, multiply working pressures by: T316/L & T317/L (at 900˚F: 0.853, at 1000˚F: 0.764).

Frequently Asked Questions (FAQ)

What are the primary applications of stainless steel coiled tubing?

Stainless steel coiled tubing is widely used in chemical, petrochemical, and food production industries. It is commonly implemented in heat exchangers to transfer heat and in high-performance racing cars and aircraft where reliable strength and durability are critical.

Why is coiled tubing preferred over traditional straight piping in tight spaces?

Its compact, coiled design makes the tubing highly flexible and easy to route and install in limited spaces. Additionally, its small diameter allows it to be used in complex layouts where traditional large, rigid pipes are impractical.

What material properties make this tubing highly durable?

It is manufactured from high-quality stainless steel, which provides excellent corrosion resistance, heat resistance, and pressure resistance, ensuring long-term reliability in harsh environments.

What grades and minimum order quantities are available for capillary tubing?

We produce capillary tubing in grades including 316L, 304, 304L, 2205, 904L, 2507, 625, and 825. The standard Minimum Order Quantity (MOQ) for production is 500 kgs.

How is the safe working pressure calculated for these stainless steel tubes?

Following the ASME code guidelines, a safety factor of four is applied to determine safe working pressures. For instance, a tube with a rated pressure capability of 21,000 PSI is assigned a safe working pressure of 5,250 PSI (21,000 PSI divided by 4).
